- A technique using (99m)Tc-mebrofenin SPECT for radiotherapy treatment planning for liver cancers or metastases.
- Shen S1, Jacob R2, Bender LW3, Duan J2, Spencer SA2.Author information 1Department of Radiation Oncology, University of Alabama at Birmingham, Birmingham, AL. Electronic address: sshen@uabmc.edu.2Department of Radiation Oncology, University of Alabama at Birmingham, Birmingham, AL.3Nuclear Medicine Division, Department of Radiology, VA Medical Center, Birmingham, AL.AbstractRadiotherapy or stereotactic body radiosurgery (SBRT) requires a sufficient functional liver volume to tolerate the treatment. The current study extended the work of de Graaf et al. (2010) [3] on the use of (99m)Tc-mebrofenin imaging for presurgery planning to radiotherapy planning for liver cancer or metastases. Patient was immobilized and imaged in an identical position on a single-photon emission computed tomography/computed tomography (SPECT-CT) system and a radiotherapy simulation CT system. (99m)Tc-mebrofenin SPECT was registered to the planning CT through image registration of noncontrast CT from SPECT-CT system to the radiotherapy planning CT. The voxels with higher uptake of (99m)Tc-mebrofenin were transferred to the planning CT as an avoidance structure in optimizing a 2-arc RapidArc plan for SBRT delivery. Excellent dose coverage to the target and sparing of the healthy remnant liver volume was achieved. This report illustrated a procedure for the use of (99m)Tc-mebrofenin SPECT for optimizing radiotherapy for liver cancers and metastases.

- Cerebellar hyperperfusion in semantic dementia.
- Vella A1, Della Nave R, Vetrugno R, Diciotti S, Boschi S, Banci Bonamici F, Mascalchi M.Author information 1a Nuclear Medicine, "Le Scotte" Hospital, University of Siena , Siena , Italy.AbstractDespite evidence of a cerebellar contribution to language, possible functional changes of the cerebellum in patients with language impairment secondary to cerebral neurodegeneration has not been investigated so far. We examined with resting perfusion single photon emission tomography one patient with semantic dementia and the data were compared with a normal subject database. Region of interest and Statistical Parametric Mapping 2 analysis showed in the patient hypoperfusion of the left temporal and parietal lobe and hyperperfusion in the superior vermis and cerebellar hemispheres (lobules IV, V, and VI). The cerebellum shows increased flow of possible compensatory significance in patients with language disturbance associated to cerebral degenerative changes.

- Tryptophan 19 residue is the origin of bovine β-lactoglobulin fluorescence.
- Albani JR1, Vogelaer J2, Bretesche L2, Kmiecik D2.Author information 1Laboratoire de Biophysique Moléculaire, Université des Sciences et Technologies de Lille, Bâtiment C6, 59655 Villeneuve d'Ascq Cédex, France. Electronic address: Jihad-Rene.Albani@univ-lille1.fr.2Laboratoire de Biophysique Moléculaire, Université des Sciences et Technologies de Lille, Bâtiment C6, 59655 Villeneuve d'Ascq Cédex, France.Abstractβ-Lactoglobulin consists of a single polypeptide of 162 amino acid residues with 2 Trp residues, Trp 19 present in a hydrophobic pocket and Trp 61 present at the surface of the protein near the pocket. This study aimed to characterize the respective contribution of the two Trp residues to the overall fluorescence of the protein. We added for that calcofluor white, an extrinsic fluorophore, which, at high concentration compared to that of the protein, quenches completely emission of hydrophobic Trp residue(s). The study was performed at different pHs by recording fluorescence steady state spectra and measuring fluorescence lifetimes of the Trp-residues using Single Time Photon Counting method. Our results indicate that addition of calcofluor white does not induce a red shift of the tryptophan(s) emission peak (332nm) but only a decrease in the fluorescence intensity. This means that Trp 61 residue does not contribute to the protein emission, tryptophan emission occurs from Trp 19 residue only. Also, excitation spectrum peak position (283nm) of β-lactoglobulin is not modified upon calcofluor white binding. These results mean that structural rearrangements within β-lactoglobulin are not occurring upon calcofluor white binding. Energy transfer between Trp 19 residue and calcofluor white occurs with 100% efficiency, i.e. the two fluorophores are very close one to each other (<5Å). This energy transfer is not Forster type. Fluorescence intensity decay of Trp 19 residue occurs with three lifetimes, equal to 0.48, 1.49 and 4.29ns at pH 2 (monomeric state). Very close values were obtained at the different studied pHs (2-12) and where β-lactoglobulin is at different quaternary structure or present in solution in a mixture of dimers and monomers. Our data are interpreted as the results of emission occurring from different substructures of the tryptophan, reached at the excited state. The populations of these substructures characterized by the pre-exponential parameters of the fluorescence lifetimes are dependent on the microenvironment of the fluorophore and on the local protein structure.
